Port 25 Blocking

    I was wondering how a ISP port 25 block would affect a routers ability to send emails? I have a RV082 and it has the option to send E-mail alerts. I know other Linksys routers have similar capabilities. There is not option to set the port for sending out the E-mail alerts so I assume it is via port 25. So with that in mind wouldn't a port 25 block effectively kill this option?

    I have been thinking about blocking port 25 at my router as a preventative measure but assume if the above is the case then that would prevent that option from working as well.

    Do we need to request Linksys add that as an option to the router firmware? Guess along with port selection we'd also need an option to validate as well(username/password).

    As a whole when an ISP blocks port 25 it is in the inbound (in relation to your router) direction. This is at least the case where i live, and we also have the ability to get it unblocked by paying for buisness service. If you have the option to tell your router what email account to use then it should work for you.
